LIST OF LABRADOR MARINE ANIMALS. 417 



B. scalariforme Mull. One specimen on the bank. 



B. cretaceum Reeve, Icon. Conch., Morrogr. Bucc, pi. 1 4, fig. 1 1 2. 

 Shell fusiform, slender, nearly three times as long as broad. A pi 

 oval, ending in a rather long, broad, oblique canal. Inner lip regu- 

 larly curved ; the columella projecting into the aperture at th ) 

 of the canal; from this projection a slight ridge runs back to the 

 other end of the aperture, following the curve of the inner lip # 

 Whorls 9, convex, especially on the upper two thirds. Spire much 

 prolonged, acute. 21 longitudinal ridges, smooth and rounded. On 

 the first whorl the ridges disappear on the lower two thirds, where 

 the minute revolving lines are more minute than elsewhere. Aper- 

 ture within, light chocolate, darker in the young, in which the 

 revolving lines are more distinct. Length §-' in., breadth y 8 ^ in. 



The slender and fusiform shape, and greater length of the spire 

 than is found in other northern species, will distinguish it. The 

 young and old were dredged alive in 1 feet mud and sand, Salmon 

 Bay. Dr. Stimpson informs me that he has seen specimens from 

 the Newfoundland Banks. It seems to be identical with Reeve's 

 species, of which he gives no locality. 



Fusus tonicities Gould. A large' specimen, tenanted by a her- 

 mit crab, was dredged in 50 feet. 



Trichotropis borealis B. and S. Frequent in 10-50 feet. 



Admete viriclula Stm. Thick heavy specimeus, an inch in 

 length, were dredged in 40-50 feet. 



Trophon scalariforme Stm. Large specimens from the Bank. 



Bulimus harpa Say. One dead shell was found in moss. The 

 only Helicid found. 



Cephalopoda. 



Ommastrephes. A squid, the fishermen informed me, some- 

 times comes ashore in swarms, or is fished up from deep water. 

 Annelida. 



Sip>tinculus n. sp. It is very different from S. Bsrnhardus 

 being larger, proportionately thicker, while the anterior third is 

 suddenly rounded and cylindrical. Found between Ascidias on a 

 hard bottom in 50 feet. 



Cerebratulus n. sp. Occurred with two other species of nemer- 

 teans, in 10 feet mud. 



Spirorbis spirillum Lam. 



S. nautiloides Lam. 



S. vilrea Stm. 



S. porrecta Stm.
